do things like the lights and water pump work ?
no means a blown fuse some place or a dropped wire
yes the batteries should charge
that should be up front under the hoood
a bad combiner relay, bad diode style battery isolator, or a bad connection
not charging from the converter when the generator is running ?
does the roof A/C work, the outlets, is the generator putting out power ?
yes ?
bad converter,
NO ? triped circuit breakers on the generator
check all your outlets, inside and outside and in the cargo bays
look for GFI outlets, the converter might not be getting any 110v power
